In this paper, we show how an Earth watching mission, dedicated to the detection and the tracking of forest fires and volcanic eruptions, and involving a constellation of low-orbiting satellites, equipped with detection and observation instruments, can be reactively and efficiently managed via the cooperation of decision modules implemented on the ground in a mission control center and onboard ...

The present-day distribution of centres of endemism is the result of an interplay between historical biogeography and contemporary environmental conditions. The relative importance of these two factors has never been established, however, for want of information on both the distributions themselves and the continental-scale measurement of environmental variables. Recently published maps of avia...

We conduct a systematic survey of the regions in which distant satellites can orbit stably around the four giant planets in the Solar system, using orbital integrations of up to 108 yr. We confirm previous results that (i) prograde and retrograde satellites orbiting within the Hill radius rH can survive out to radii of ∼ 0.5rH and ∼ 0.7rH, respectively; (ii) stable orbits do not exist at high e...

Tropical cyclones spend most of their life cycle over the tropical and subtropical oceans. Because of the lack of in situ data in these regions, satellite observations are fundamental for tracking and estimating the intensity of these storms for real-time forecasting and monitoring climate trends. This chapter reviews methods for estimating tropical cyclone intensity from satellites, including ...

Low Mass X-ray Binaries (LMXBs) with either a black hole or a neutron star show power spectra characterised by Quasi Periodic Oscillations (QPOs). Twin peak high frequency QPOs are characterised by frequencies that are typical for matter orbiting within 10 rg from the compact object. We consider clumps of material orbiting a Schwarzschild black hole, that are deformed by tidal interaction. We p...

This study aims to evaluate and analyze the orbit predictions of selected satellites: geodetic, Global Navigational Satellite Systems (GNSS), scientific low-orbiting, which are tracked by laser stations. The possibility conducting satellite ranging (SLR) artificial satellites depends on access high-quality orbits. provide information stations where aim telescope in search a get returns from ret...
